I'm meeting with someone this weekend to buy their juvenile BP, which he said is about 1 1/2 feet long and maybe a year or two old. Although I've worked and owned snakes before, is there anything I should look out for before I actually fork over the cash for it? I intend to handle it to make sure it's not super-aggressive or something, though he's only selling it because of upcoming baby expenses (he says). It comes with a large aquarium, heat rock, and some kind of hollow dome where it can go in and hide. The bedding looks like some kind of chopped-up shredded material. It also comes with a lock-lid, water dish, and heating pad. But I want to make sure the snake is healthy and easy to handle, since I have small children.
